I will be placing the inflow/outflow together to create circular flow in the cube; however, since I am using an inline diffuser and my length and width are equal...does it matter if I put it on the back pane to one side, or either of the side glass panes to the back?

Anybody know the proper lily pipe placement for a cube

Since it's a cube I would think any corner will do.

A cube will probably be easy, just stick the inflow and outflow right next to each other and you'll probably get what you want with little effort. The only thing to watch out for would be hardscape or tall plants that might block the path of the flow.
